1. Yes, I want roar for fairy types, because groudon's roar is the only hope for stopping baton pass teams and geomancy xerneas (Yes, I know ditto can also stop geomancy xerneas, but groudon is there if I used ditto on zacian or something)
2.I need defog on lugia for the other pokemons, because sometimes stealth rocks can be annoying, and Sticky webs is always extremely annoying with this team, basically every pokemon I bring to the battlefield is always slower than the opposing pokemon (Except flying types because the only hazard that can hit flying types or levitate pokemons is stealth rocks). and remember, this is a hyper offense team so speed is very important.
